Joburg residents warned of prolonged power outages

JOHANNESBURG - With South Africa having gone load shedding free for more than 50 days, City Power has warned Johannesburg residents of prolonged power outages if they don't use electricity sparingly.

Johannesburg's power utility says it is facing a strain on its system due to high consumption and a recent drop in temperatures. 

The utility says essential services will be mostly affected by the outages.
